Research on the simulation of the fractional order PID control to permanent magnet motor

This paper research the model and control of permanent magnet synchronous generator, is based on the frac-tional order PID control which is taken into the permanent magnet synchronous motor and instead of the traditional PI adjuster, establish a permanent magnet synchronous generator mathematical model under the same speed rotating dq co-ordinate to obtain a drive signal generator required by PWM way ,realize power transmission, then using toolbox of Mat-lab/Simulink PMSM system to simulate. Results showed that fractional order PID controller had excellent dynamic per-formance of the control system and robustness which was better than traditional PI adjuster.
